Castlevania: Harmony of Despair is now being touted as a proud participant in the Xbox Live Summer of Arcade promotion, a PSN version of the title may not be out of the question. In an E3 interview with Destructoid, producer Koji Igarashi explained "there might be a possibility with that. I hope this one sells, and then we can think about PSN."
So, there you have it, PS3 fans. If you want the best chance of getting Harmony of Despair on your platform of choice, all you have to do is first buy it on XBLA. Easy enough, right?
